[0058] Fig. 11A is a schematic view illustrating a non-circular aperture stop according to the present disclosure. The effective radius of the aperture stop on the long axis is D, the effective radius of the aperture stop on the short axis is L, and D is larger than L.

[0059] Fig. 11B is a schematic view illustrating another non-circular aperture stop according to the present disclosure. The effective radius of the aperture stop on the long axis is D', the effective radius of the aperture on the short axis is L', and D' is larger than L' .

[0060] The aforementioned features of the image capturing system lens assembly can be utilized in numerous combinations so as to achieve corresponding effects.

[0061] According to the image capturing system lens assembly of the present disclosure, the object side and the image side refer to the direction along the optical axis.

[0062] According to the image capturing system lens assembly of the present disclosure, the optical elements thereof can be made of glass or plastic material. When the optical elements are made of glass material, the distribution of the refractive power of the image capturing system lens assembly may be more flexible to design and the effect of external environmental temperature on imaging can be reduced. Technologies such as grinding or molding can be used for producing glass optical elements. When the optical elements are made of plastic material, manufacturing costs can be effectively reduced. Furthermore, surfaces of each optical element can be arranged to be spherical or aspheric (ASP). Arranging the spherical surfaces can reduce difficulties in manufacturing while arranging the aspheric surfaces can result in more control variables for eliminating aberrations and to further decrease the required quantity of optical elements; also, the total track length of the image capturing system lens assembly can be effectively reduced. Processes such as plastic injection molding or molded glass lens can be used for making the aspheric surfaces.

[0063] According to the image capturing system lens assembly of the present disclosure, if a surface of an optical element is aspheric, it means that the surface has an aspheric shape throughout its optically effective area, or a portion(s) thereof.

[0064] According to the image capturing system lens assembly of the present disclosure, additives may be selectively added to the material of any one (or more) optical element to produce light absorption or light interference effects, so as to change the transmittance of said optical element in a particular wavelength range of light, and to further reduce stray light and chromatic aberrations. For example, an additive that can filter off light in the wavelength range of 600-800 nm may be added to reduce extra red or infrared light, or an additive that can filter off light in the wavelength range of 350-450 nm may be added to reduce blue or ultraviolet light in the optical elements. Thus, additives can prevent unwanted disrupting light in particular wavelength ranges affecting the final image. In addition, additives may be evenly mixed in the plastic material for manufacturing optical elements with an injection molding process. In addition, additives may also be added to a coating on the surface of a lens element to provide the aforementioned effects.

[0065] According to the image capturing system lens assembly of the present disclosure, the image capturing system lens assembly can include at least one stop, such as an aperture stop, a glare stop or a field stop, so as to favorably reduce the amount of stray light and thereby improve the image quality.

[0066] According to the image capturing system lens assembly of the present disclosure, an aperture stop can be configured as a front stop or a middle stop. The front stop disposed between an imaged object and the first optical element can provide a longer distance between an exit pupil of the image capturing system lens assembly and the image surface, so that the generated telecentric effect can improve the image-sensing efficiency of an image sensor, such as a CCD or CMOS sensor. The middle stop disposed between the first optical element and the image surface is favorable for enlarging the field of view of the image capturing system lens assembly, thereby providing the image capturing system lens assembly with the advantage of a wide-angle lens.

[0067] An aperture control unit may be disposed in the image capturing system lens assembly of the present disclosure. The aperture control unit may be a mechanical part or optical moderation part, in which the size and shape of the aperture may be controlled by electricity or electronic signals. The mechanical part may include moving parts such as blades, shielding sheets, etc. The optical moderation part may include shielding materials such as filters, electrochromic materials, liquid crystal layers, etc. The aperture control unit can control the amount of incoming light and exposure time so as to further improve the image quality. Meanwhile, the aperture control unit may represent the aperture in the present disclosure that can adjust the image properties such as depth of field or exposure speed by changing the f-number of the image capturing system lens assembly.

[0068] According to the image capturing system lens assembly of the present disclosure, when the optical element has a convex surface and the region of convex shape is not specified, it indicates that the surface can be convex in the paraxial region thereof. When the optical element has a concave surface and the region of concave shape is not specified, it indicates that the surface can be concave in the paraxial region thereof. Likewise, when the region of refractive power or focal length of an optical element is not specified, it indicates that the region of refractive power or focal length of the optical element can be in the paraxial region thereof.

[0069] According to the image capturing system lens assembly of the present disclosure, at least one reflective element capable of altering the optical path, such as a prism or a reflective mirror, can be optionally provided on the optical path between the imaged object and the image surface, wherein the surface shape of the reflective element or reflective mirror can be flat, spherical, aspheric or freeform. Then, the image capturing system lens assembly can be provided with more flexibility for its space arrangement, so that minimization of electronic devices is not limited by the total track length of the image capturing system lens assembly.

[0070] According to the image capturing system lens assembly of the present disclosure, the image surface of the image capturing system lens assembly, based on the corresponding image sensor, can be a plane or a curved surface with an arbitrary curvature, especially a curved surface being concave facing the object side. Meanwhile, the image capturing system lens assembly of the present disclosure may optionally include one or more image correction components (such as a field flattener) between the image surface and the optical element closest to the image surface for the purpose of image corrections (such as field curvature correction). The optical properties of the image correction components such as curvatures, thicknesses, indices, positions and shapes (convex or concave, spherical or aspheric, diffractive surface and Fresnel surface, etc.) can be adjusted according to the requirement of the imaging apparatus. Preferably, an image correction component may be a thin plano-concave component having a surface being concave toward the object side and arranged near the image surface.

[0071] One or more optical elements can be provided in the image capturing system lens assembly of the present disclosure to limit the forms of light passing through the system. The aforementioned optical element may be (but is not limited to) a filter or a polarizer, and may be provided in the form of a single piece, a composite component or a thin film, but is not limited thereto. The aforementioned optical element can be disposed on the object side or image side of the image capturing system lens assembly or alternatively between the lens elements of the assembly to control specific forms of light to pass through, so as to meet different application needs.

[0072] The image capturing system lens assembly of the present disclosure can comprise at least one of an optical lens element, an optical element or a carrier, which includes a low reflection layer disposed on at least one surface thereof. The low reflection layer can effectively reduce the stray light generated by light reflection at the interface. The low reflection layer can be disposed on the non-effective area of the object-side surface or the image-side surface of the aforementioned optical lens element, or on a connecting surface between the object-side surface and the image-side surface. The aforementioned optical element can be a light blocking element, an annular spacer element, a barrel element, a cover glass, a blue glass, a filter/color filter, an optical path folding element, a prism, or a mirror. The aforementioned carrier can be a lens assembly carrier, a micro lens disposed on the image sensor, or a glass sheet surrounding the substrate of the image sensor or used for protecting the image sensor.
